Menu Tree; Led Status Screen; Double Arrows On The Screen - ZyXEL Communications U-336S User Manual

Menu Tree

In command state, there are three main menu trees. The DIALING
menu is the default, and can be accessed after the modem is
powered on or reset. The second is the CONFIGURATION menu,
which also includes a submenu. The third is the DIAGNOSTIC
menu. All three menu trees can be accessed by pressing the up or
down arrow key. When the modem is in the data state, there is one
idle screen and four data state status screens which can be accessed
by pressing the left or right arrow key.

LED Status Screen

Either in idle state or data state, there is an LED status screen that
can be accessed and displayed by pressing the left or right arrow
key at the menu's top level. This LED status screen has five status
indicators - DCD, DSR, CTS, RTS, and SQ. These status
indicators are identical to the LED indicators of the non-LCD
modems. Values in one of the other screen displays may give much
more detailed information than some of these status indicators; e.g.,
a data state screen means DCD is on, and an idle screen means
DCD is off; SQ is better explained by the S/N ratio reading and the
other impairment readings of data screen 2.

Double Arrows on The Screen

In some menu screens, you will see double left arrows (<<) or
double right arrows (>>). This means there are more items on the
left or right. Use the left or right arrow key to select them. If you
can only see a double right arrow, this indicates that the current
item is the first item of the menu. By pressing the left arrow key,
the screen will wrap over to the last item. On the other hand, if you
register the chosen selection and is very similar
to the Carriage Return key or Enter key on a
standard keyboard.
